Question

Solve 50q-43=52q-81

Answer 1

The answer is 19
50q-43=52q-81 Subtract 50q from both sides
-43=2q-81 Add 81 to both sides
38=2q Divide by 2 on both sides
19=q

Answer 2

Move the variables to one side and the constants to the other

50q - 43 = 52q - 81

50q (-52q) - 43 (+43) = 52q (-52q) - 81 (+43)

50q - 52q = -81 + 43

-2q = -38

isolate the q, divide -2 from both sides

-2q/-2 = -38/-2

q = -38/-2

q = 19
